Hint: It’s not the flu.

Tuberculosis (TB) is one the world’s most common diseases mainly because it is so highly infectious-it’s spread with a mere cough or sneeze. It’s second only to HIV as the leading infectious killer of adults worldwide, and it is the third largest cause of death among women aged 15 to 44.

The World Health Organization estimates that two billion people-that’s one-third of our planet’s population-are infected with the bacteria that cause TB. Ten percent of these carriers will become sick, and if left untreated, half of those will die from the disease.

Conventional medicine is panicking because TB is becoming resistant to multiple drugs and fear it may become ‘virtually untreatable.
